AUTOMATIC WINDOW WINDOW

  The present invention relates to a window with automatic ventilation for a building, comprising a mobile frame on a fixed frame, three windows

  parallel mounted in this frame, a first gap between the glass pane

  and the intermediate window and a second gap between the glass pane

  intermediate and the inner pane, a baffle ventilation circuit formed by at least one inlet conduit disposed at the bottom of the window for connecting the outside air to the first interval, by at least one intermediate duct formed in the upper part of the movable frame for connecting the first gap to the second, and by at least one outlet duct disposed at the bottom of the window to connect the second gap to the building's interior air, at least one adjustment and shutter flap disposed in this circuit, and control means of this component, provided with a control member on

the inner face of the window.

  French Patent No. 2,437,484 already discloses a window of this kind, in which the inlet and outlet ducts are formed in the movable frame of the window. This chassis is equipped with arranged valves

  to limit or stop the flow of air between the windows, as well as

  manual control ganes of these flaps. This window allows ventilation of the room in which it is mounted, while ensuring excellent sound insulation. However, it has various disadvantages from the point of view of its construction and use. In particular, the lower part of the frame, enclosing the valves and the control members, is relatively large, which reduces the free surface of the windows. In

  In addition, the weight of the mobile frame is higher than that of a working chassis.

  ditional. On the other hand, it is very difficult to resolve satisfactorily

  making the sealing problems at the bottom of the outer pane, so that the operation of the flaps or a good durability of the window

  are not insured if you do not perform regular maintenance. In addition

  their, with its relatively heavy and bulky chassis, this device is

  inconvenient on a window of the guillotine type.

  Therefore, the present invention aims to remedy these inconveniences.

  in providing a window with an air circuit that allows

-2 - 2572456

  - 2 - aeration when the window is closed, this window being of construction

  Simple and robust, requiring little maintenance, with a relative chassis

  light, while ensuring good thermal and sound insulation.

  For this purpose, the present invention relates to a window of the type mentioned in the preamble, characterized in that the fixed frame comprises, on its face

  outside, at least one entrance opening which is connected to the first

  valle by the inlet duct, and in that said flap is mounted on the

  dre fixe, as well as its control means.

  Preferably, the shutter is arranged to be able to seal the opening of

  Tree. This flap can be pivoted about a horizontal axis on at least

  a support integral with the fixed frame. In particular, the component is

  tagously on the outside of the window. Preferably, the axis of pivoting of the flap is located higher than the opening to be closed, the flap being arranged in such a way, with respect to its axis of pivoting, that it

  tends to close by its own weight.

  The shutter control means preferably comprise a pull tab comprising a rod arranged to slide in the fixed frame, a handle

  attached to the end of this pull-tab on the inside of the window, the end

  outer mating the rod being in contact with the flap, and a latching detent mechanism for locking the pull tab in at least two determined axial positions. In this arrangement, combined with a flap pivoting about a horizontal axis, the second end of the rod and the flap may comprise coupling means for driving the flap by the pull tab in one direction and the other. In this case, the stem

  is advantageously connected to the handle by spring means.

  According to a preferred embodiment, the output duct passes into

the fixed frame of the window.

  This embodiment has various advantages which will be described later. In particular, an electric fan can thus be connected to the ventilation circuit. This fan can be mounted in the fixed frame

  from the window. If the shutter is arranged to be able to close the opening of

- 3 - 2572456

  the fan can be arranged in parallel with the said opening of

  trea and be connected on the one hand to an outer opening equipped with a movable shutter member and, on the other hand, to the inlet duct, the fixed frame of

  the window being equipped with means for controlling the fan and the or-

  shutter. According to another variant, the fan can be part of an air conditioning unit. According to another embodiment, the output conduit passes only

in the mobile frame.

  In all cases, the air circuit may comprise a removable filter arranged

in the fixed frame.

  In a window according to the present invention, the three panes preferably have the same dimensions. The mobile frame may comprise three elements which are articulated with respect to each other, each of

  these elements serving as a frame for one of the windows.

  The present invention and its advantages will be better understood by means of

  the following description, by way of example, of various forms of

  embodiments with reference to the accompanying drawing, in which

  FIG. 1 is a transverse vertical sectional view of a form of

  Preferred embodiment of the window according to the invention. FIG. 2 is a vertical sectional view along line II-II of FIG. 1, FIG. 3 is a schematic perspective view showing means for coupling the pull tab and the shutter,

  FIG. 4 is a schematic view in horizontal section through the

  FIG. 5 is a diagrammatic view in vertical section, similar to FIG. 1, 4a of an alternative embodiment, and Figure 6 is a schematic vertical sectional view of another form

of realization.

  The window shown in FIG. I comprises a fixed frame I comprising metal sections 2 to 9 and sealing profiles 11, 12 and. 13 made of synthetic material or rubber, and a movable frame 14 mounted on

  the frame fixed in an articulated manner, for example by hinges (not shown in

  tees) so that it can be rotated to open the window. The frame

  mobile sis 14 comprises in fact three frame members 15, 16 and 17 which surround and support respectively three parallel panes, namely a

  outer pane 18, an intermediate pane 19 and an inner pane 20.

  The frame members 15, 16 and 17 are secured together along the sides of the window in a manner known per se, for example by hinges along one side and screws along the other. to allow them to be removed for cleaning the inside of the window. Between the windows, a first gap 21 is defined between the outer pane 18 and the

  intermediate window 19, and a second gap 22 located between the glass pane

  mediate 19 and the inner pane 20.

  Above the first gap 21, the mobile frame has one or more

  Slots 23 formed between the frame members 15 and 16. Similarly, one or more slots 24 are provided between the frame members 16 and 17, above the second gap 22. The respective slots 23 and 24 are in communication, inside the mobile frame 14, by a conduit

  intermediate 25 located above the intermediate window 19 and its ele-

  Alternatively, the intermediate duct 25 could also be constituted by slots passing through the upper part of the element.

  16. Thanks to the intermediate duct 25, the air contained in the first

  first interval 21 is in communication with the air which is in the se-

cond interval 22.

  Similarly, the lower portion of the mobile frame 14 has one or more slots 26 formed between the frame members 15 and 16 below the first gap 21 and one or more slots 27 formed

  between the frame members 16 and 17 below the second gap 22.

  When the window is closed, as shown in fig. 1, the slots 26 and 27 are not in communication below the intermediate window 19, since they are separated by the intermediate frame member 16 against a sealing profile 12 of the fixed frame. Preferably, the slots 23, 24, 26 and 27 are continuous across the width

  from the window. However, they can be split by providing for several

  consecutively, separated by spacers that provide support for the

  intermediate frame member 16 against frame members 15 and 17

  to increase the rigidity of the mobile frame.

  According to the invention, the fixed frame I comprises, on its outer face,

  re, an inlet opening 30 which is connected to the first gap 21 by an inlet duct 31 extending both in the fixed frame and, through the slot 26, in the movable frame. In the example shown, the inlet duct 31 passes through a horizontal opening 32 of the fixed frame, in which is

  disposed a removable filter 33 schematically shown in broken lines.

  no longer intended to stop dust, insects, etc. The openings 30 and 32 preferably extend over most of the

  the width of the window, but they may also consist of

several juxtaposed openings.

  Similarly, the lower part of the fixed frame 1 comprises, on the inner side of the window, an outlet opening 34, a horizontal opening and an outlet duct 36 which connects the second gap 22 to the outlet opening 34 passing through. by the slot 27. Thus, there is an air circuit from the inlet opening 30 to the outlet opening 34 through the inlet duct 31, the first gap 21, the intermediate duct 25, the second interval 22 and the outlet duct 36, circuit that the air can travel as

  the arrows in fig. 1, or in the opposite direction in some cases.

  This circuit comprises a large number of baffles, in particular by the fact

  air introduced into the lower part of the window is diverted

  than at the top, then must go down, which ensures a very strong

  attenuation of external noise transmitted by the air towards the interior of the building.

  -6 - To partially or completely close the inlet opening 30, to allow to adjust or interrupt the flow of air, a flap 40 is mounted on the outer face of the fixed frame of the window. This flap 40 is constituted by a metal section or synthetic material which extends over most of the width of the window. Its back side

  carries a planar portion arranged to completely cover the opening or openings

  input heads 30 extending along the window. Along its upper edge

  the flap 40 comprises a cylindrical bead 41 which defines an axis

  horizontal pivoting. This bead is introduced into a cylindrical groove

  than one or more supports 42 fixed to the frame of the window. On the other hand,

  the lower portion 43 of the flap 40 has an enlarged shape, of such

  that the center of gravity of the shutter is shifted outward by

  relative to the center of pivoting, so that the flap 40 tends to close

sea by its own weight.

  To control the position of the flap 40, the window according to the invention

  simply carries a pull tab 44 which is mounted in the lower part of the fixed frame I. In the example illustrated in FIG. 1, the pull tab 44 comprises a support 45, a sliding sleeve 46 provided with a knob-shaped handle 47 on the inside of the window, and a sliding rod 48 whose outer end bears against the flap 40. L other end of the rod 48 has a head 49 which is clamped in the sleeve 46 between

  two springs 50 and 51 by means of a set screw 52, in order to attenuate the trans-

  mission to the zipper 44 shocks that can be produced by the flap 40

on the stem 48.

  The pull tab 44 further comprises a locking mechanism with notches

  putting a zipper lock in several axial positions determined

  corresponding to several positions of component 40. This mechanism is

  lustrous by figs. 1 and 2. The support 45 of the pull tab comprises, in a

  lateral wise, a device called "ball screw" formed in known manner by a ball 54, a coil spring 55 and a screw 56 providing a spring pressure against the ball. The sleeve 46, arranged to slide axially

  in the support 45, has on its periphery a series of circular grooves

  57 in which the ball 54 can engage to lock the position

  axial direction of the bushing 46. Thus, each groove 57 corresponds to a posi-

-7-

  determined determination of the pull tab 44 and the flap 40.

  In fig. 1, the pull tab 44 is shown in the closed position of the

  40. When the zipper is moved by moving the knob 47 to the position

  47a drawn in broken lines, the end of the rod 48 pushes the flap 40 to an open position 40a drawn in broken lines, then it holds in this position under the effect of the ball screw engaged in the corresponding groove 57. The air flow through the window is then opened and aeration occurs according to the conditions prevailing outside and inside the building. Most of the time, the air is over

  hot inside the building and it has ventilation ducts.

  tion, so that the air tends to enter through the window according to the invention and to circulate as indicated by the arrows of FIG. 1. To a certain extent, the user can adjust the air flow

  by means of the flap 40 by acting on the pull tab 44.

  In the embodiment described above, the shutter is simply in

  support against the end of the rod 48 of the zipper or against the outer face

  framework, so that it can be raised in some cases, for example

  full by a violent gust of wind. Such a movement can cause

  unpleasant noises or drafts in the building. Fig. 3 illus-

  be a provision to remedy this disadvantage by milling,

  in the rear part of the flap 40, a groove 60 oriented perpendicularly

  the pivot axis of the flap and having a sensitive section

  cylindrical, narrower at the surface of the flap than at depth. At its lower end, the groove 60 has an insertion orifice 61

  whose diameter is equal to that of the cylinder entering the groove 60.

  The rod 48 used in this case is provided at its end with a spherical knob 62 which is introduced through the insertion orifice 61 and which then remains trapped in the remainder of the groove 60, so that the component 40 does

  can rotate in one direction or the other. The orifice 61 is disposed sufficiently

  low so that it is never reached by the spherical knob 62,

  except that the rod 48 is pulled outwards by strongly compressing the resistor

spell 51 (Fig. 1).

  Compared to the prior art mentioned above, the window shown

- 2572456

  8 - in fig. 1 has significant advantages. The dimensions and weight of the mobile frame 14 are similar to those of a triple pane window without aeration circuit. In addition, its sealing device is also the

  same as the usual windows, so there is no problem

  me especially. Finally, the frame elements can be made with the

  metal profiles, in which it is not necessary to

  manage transverse ducts or house mechanisms.

  Another important advantage of the present invention is the fact that

  It is easy to connect an electric fan to the ventilation circuit, since it necessarily passes through fixed parts of the window. For example, this fan may be arranged in the building and be connected to the outlet duct 36 either through the outlet opening 34 or by another opening disposed near an angle of the window. Such a fan

  can, for example, be an element of an air conditioning unit.

  Fig. 4 illustrates an advantageous arrangement of a fan 64 installed in the fixed frame of the window. This figure shows schematically in horizontal section the inlet duct 31 of the air circuit, the inlet opening 30

  being closed by the flap 40. The fan 64 is mounted in a compartment

  separate at a corner of the window, and is actuated by a

  electrical generator 65 which is also housed inside the frame 1. On the side of the suction, the fan 64 is connected to a suction opening

  66 made on the outer face of the frame 1 and equipped with a blind shutter

  ration 67 which may be of similar construction to that of component 40. The

  The auger 64 has a delivery pipe 68 which is connected

  directly to the inlet duct 31. Finally, a two position pull rod 69 is connected to the flap 67, and a lever 70 controlling the operation of the motor 65, so as to simultaneously actuate the opening of the shutter

  67 and switching on the fan 64.

  The device shown in FIG. 4 can work without the help of

  as described above. To do this, it suffices to open the flap 40. If it is desired to produce a forced aeration, the flap 40 is closed by means of

  the pull tab 44 and the shutter 67 is opened by means of the pull tab 69, which

  When the fan 64 is turned on, it sucks in the outside air through the orifice 66 and pushes it towards the interior of the building through the circuit

  of air passing through the window. As this circuit is relatively long and pre-

  If there are several baffles, the noise produced by the fan is muffled.

  Figs. 5 and 6 illustrate two other embodiments of a window

  according to the invention, in which the fixed frame and the movable frame are

made of wood.

  The window illustrated in fig. 5 has a fixed frame 71 and a frame

  mobile 72 which carries the three panes 18, 19 and 20 arranged as previously

  ously. The frame 72 is made of two elements 73 and 74 which are

  on one another in the traditional way using hinges. Lavitre inter-

  19 is mounted between the two frame members 73 and 74 using

an auxiliary executive 75.

  In principle, the ventilation circuit passing through this window is identical.

  tick to that of the window of fig. 1. It comprises in particular an inlet duct 76 and an outlet duct 77 which pass through both the fixed frame

  and the movable frame in the lower part of the window. The conduit of

  trea 76 is provided with a removable filter 78 and a control and adjustment flap.

  80 controlled by a zipper 81. In the upper part of the frame

  72, an intermediate conduit 82 interconnects the two intervals 21

and 22 located between the windows.

  The conduits 76, 77 and 82 have simple shapes and can be easily made by milling longitudinal rectangular slots in the wood. Depending on the width of the chassis, these slots can be continuous or

  be in the form of a succession of several slits, between

  What remains are struts providing sufficient rigidity to the

  not to be. It should be noted that the construction illustrated here is extremely

  simply simple. In addition, it allows to use three windows having the same dimensions, which is particularly interesting from the point of view

from the manufacturer's stock.

  The examples described with reference to FIGS. 1-5 also illustrate another important advantage of the present invention. Thanks to the layout

- 10 -

  vertical lines of the inlet and outlet ducts in the lower part of the

  sis mobile and thanks to the absence of control organs in this frame, these constructions are quite suitable for the realization of a ventilation circuit

  in a window of the guillotine type, that is to say the chassis of which is

  bile vertically to the frame. Of course, this ventilation device is also usable for a window whose frame slides in the horizontal direction.

  The window shown in FIG. 6 has a fixed frame 91 and a frame

  sis 92 which are made very similar to the elements cor-

  corresponding to the window of FIG. 5. The upper part of these two

  are identical. On the other hand, in the case of FIG. 6, the window comprises an outlet duct 93 which extends only in the mobile frame 92, while the inlet duct 76 is identical to that which has been described in FIG.

  reference to FIG. 5. In certain cases, this provision makes it possible

  the height of the lower part of the window taking advantage of the fact that the greater thickness of the movable frame 92 is always on the inside of the window, while the greater thickness of the frame 91 is

found on the outside.

  The present invention is not limited to the embodiments described, but it extends to any modification or variant obvious to those skilled in the art. In particular, the shape and arrangement of the adjustment and shutter flaps. , as well as their control members, can be the subject of multiple variants. These shutters are not necessarily placed on the outer face of the window; they can also be arranged on the other side or in one of the inlet or outlet ducts, inside the fixed frame. - He - 2572456
